If the generated heat cannot be dissipated timely, the accumulated heat will enhance the battery temperature, and thus aggravate the chemical reactions within the battery. This will shorten the life span of the LIB and further reduce its safety performance, increasing the likelihood of fire and explosion accidents [7], [8], [9] .
Today, liquid cooling is an effective heat dissipation method that can be classified into direct cooling [7] and cold plate-based indirect cooling (CPIC) methods [8] according to the contact relationship between the cooling device and the heat source.Typically, direct cooling of an immersed battery pack into a coolant is an expensive cooling method.
